Embodiment Construction
[0033] The current international competition in the information industry has increasingly manifested itself as a competition for science and technology. As a strategic and forward-looking important emerging technology industry, the speech recognition industry has always been the focus of attention of the scientific and industrial circles at home and abroad. The present invention relates to a new type of speech recognition technology and corresponding devices. The present invention proposes to use a micro-nano sensor to collect the vibration signal generated by the vocal cords during pronunciation, instead of capturing the propagation signal of speech in the air through the acquisition module as in the traditional speech recognition technology. Then the vibration signal is amplified, filtered and preprocessed, the characteristic signal is extracted and identified and analyzed by time domain analysis method, frequency domain analysis method, etc., so as to obtain a simple, feasibl...
